Boston Multivision Gas Permeable Contacts

Boston Multivision RGP Contact Lenses from Bausch & Lomb

Boston Multivision contacts are a design of boston contact lenses that provides crisp vision at distance, intermediate and near vision for presbyopes.

If you're at an early stage of presbyopia and have sensitive eyes, dry eyes, or astigmatism this daily wear, gas permeable lens is suitable for you. The lens is made from Boston ES, oxygen permeable material that resists deposits. This results in fresh lenses that are comfortable to your eyes.

How Does Multivision Contact Lens Work?

Bausch & Lomb Boston Multi Vision is designed to follow the natural topography of the cornea, with a junction-less, aspheric zones in its back surface. This design allows the lens to be alignment-fit with central portion of the cornea, similar to the design of single-vision contact lenses.

The lens consists of

Elliptical optic zone that provides distance vision,
Hyperbolic zone that provides the plus power,
Fillet curve is an area between the hyperbolic
Elliptical fitting zone that allows for controlled edge lift,
Controlled edge lift that is similar throughout the base curve range.

The front surface of this lens combines elliptical, center optic zone and hyperbolic zone. When the lens is centered over your pupil for distance viewing, your distance and intermediate vision is corrected simultaneously. When you look down to read, the lens translates up for correcting your near vision.

Features and Benefits

Designed for simple fit. Boston Multivision uses an alignment fitting philosophy. So your eye doctor only need to specify power and base curve that means less doctor visit for lens fitting.

Designed for patient comfort. The lens is designed with a back surface profile that's engineered to control edge lift for optimal edge clearance and comfort.
